Location Aware Routing in Intermittently Connected MANETs

Existing mobile ad hoc routing protocols like AODV, DSR and GPSR allow nodes to communicate with one another with an assumption that there exists a connected path from source to destination. Due to limited transmission range, power limitations, mobility of nodes, and the wide physical conditions over which ad hoc networks must be deployed; in some scenarios it is likely that this assumption is invalid leading to intermittent connectivity and absence of end-to-end connections. In this paper, the authors propose a geographical routing algorithm called Location-Aware ROuting for Delay-tolerant networks (LAROD), enhanced with a location service, Location Dissemination Service (LoDiS), which together are shown to suit an Intermittently Connected MANET (IC-MANET).
